JOHN H. LINDSEY, OF KEVIL, KENTUCKY.

HARROW.

To all whom it may concern:

Be it known that I, JOHN H. LINDSEY, a citizen of the United States,residing at Kevil, in the county of Ballard and State of Kentucky, haveinvented a new and useful Harrow, of which the following is aspecification.

It is the object of the present invention to provide an improvedconstruction of l1ar row and the invention aims more specifically toprovide a harrow which may be readily converted into a drag and when soconverted may be employed not only as a drag but in numerous other ways,for example, as a stone boat.

It is a further object of the invention to provide, in a harrow havingoscillatory tooth bars, means for holding the tooth bars in one oranother of two positions and in so constructing and arranging such meansthat the same will not be subjected to any considerable strain when thedevice is in use either as a harrow or as a drag.

In the accompanying drawings, Figure 1 is a top plan view of a harrowconstructed in accordance with the present invention, and Fig. 2 is avertical sectional view therethrough on the line 22 of Fig. 1.

In the drawings, the harrow is illustrated as comprised in part of aframe including side sills 5 which are connected at their forward endsby a draftframe 6 having an arcuate forward portion 7 to which may beattached the draft appliances. The said side sills 5 of the frame of theharrow are further braced by means which will be presently described butbefore proceeding with a description of such means reference will be hadto other portions of the harrow frame. The portions just mentioned areembodied in the side bars 8 which are secured at their forward ends oneto each of the side beams 5 of the frame at the forward end thereof andextend rearwardly outwardly at an angle from the said respective sidebeams as is clearly shown in Fig. 1 of the drawings, their rear endsbeing considerably spaced from the rear ends of the side beams and thesaid side beams being parallel throughout their entire lengths.

The side beams 5 of the frame of the harrow and also the side bars 8thereof serve to support oscillatory tooth bars which are indicated bythe numeral 9. These tooth bars are arranged transversely of the harrowframe one behind the other and they in- Specification of Letters Patent.

crease in length successively in order toward the rear of the harrowframe. The foremost one of the tooth bars is journaled at its ends inthe side bars 5 as indicated by the numeral 10 whereas the tooth barsrearwardly of this foremost one are journaled. at their ends in the sidebars 8 of the harrow frame, they being formed however inwardly of eachend with a cylindrical reduced bearing portion 11 which is received insuitable bearings 12 provided upon the side beams 5 of the harrow frame.Each of the tooth bars 9 carries a plurality of teeth 13 which projectat right angles therefrom, the said tooth bars being polygonal in crosssection for a purpose which will be presently explained; except at thepoints of formation of the bearing portions 11 where they arecylindrical in cross section.

It will be understood from the foregoing that by forming the journalportions 11 cylindrical and of a diameter not greater than the thicknessof the tooth bars at other points, the side beams of the harrow framewill be firmly held against displacement.

As heretofore stated, the tooth bars 9 are mounted for oscillation andin order that they may be simultaneously rocked, there is fixed uponeach of the bars, at a point be tween its ends, a bracket lfl'. to whichis pivotally connected a rod 15, it being understood that this rod iscommon to all of the tooth bars. The pivotal connection is preferablyhad by forming the bar at points in its length with eyes 16 in which arereceived ears 17 forming portions of the brackets 14. At its rear end,this rod is provided with an upstanding handle 17 which may be graspedwhereby the rod may be pulled rearwardly or shoved forwardly to rock thebars simultaneously in a corresponding direction.

A rod 18 is mounted transversely of the frame of the harrow at theforward end thereof and pivoted at its forward end to this rod is alocking bar 19 which is formed at points in its length, in its underedge, with notches 20 which are of the same outline as the tooth bars,in cross section. This locking rod 19 may be swung upon the rod 18 aswill be presently understood but is incapable of longitudinal movementit being particularly braced against such movement by the rod 18 whichrod has its intermediate portion located forwardly of its end portionswhich are secured in the said side beams 5 of the harrow frame. Thismanner of forming the rod 18 positively insures against its ends beingpulled from the said side beams 5 and further insures against bucklingof the rod.

It will be understood that inasmuch as the harrow bars, in crosssection, have the same general outline as have the notches in thelocking bar 19, the said tooth bars may seat in the notches when in theposition shown in full lines or in dotted lines in Fig. 2 of thedrawings. In the former instance the teeth upon the bars projectdownwardly whereby the device may be utilized as a harrow but in thelatter instance these teeth project rearwardly as shown in dotted lineswhereby they will not come into working engagement with the soil. Thelocking bar 19 is provided at its rear end with a handle 21 by means ofwhich it may be readily swung upwardly to disengage from the tooth barsand permit of the said bars being rocked to full or dotted line positionas shown in Fig. 2.

As a means for holding the locking bar 19 in engagement with the toothbars 9 of the harrow whereby these bars will be firmly held againstoscillatory movement when the harrow is in use, there is provided alatch bar 22 which is pivoted at one end as at 23 to one of the sidebeams 5 of the harrow frame and at its other end engages beneath akeeper 24L upon the other side beam 5. The said bar 22, as will bereadily understood, extends above the locking bar 19 and prevents upwardmovement of the bar out of engagement with the tooth bars and at itslast mentioned end said latch bar is formed with a head 25. It isexpedient that some means be provided for holding the latch bar againstdisengagement from the keeper 241 and to this end I have provided apivoted hook 26 which is carried by that beam 5 upon which the keeper241 is mounted and which engages with the said latch bar 22 directlyinwardly of its head 25 and holds it against disengagement from thekeeper 24; as stated.

From the foregoing description of the in vention it will be readilyunderstood that the implement may be converted from a harrow into a dragby swinging upwardly the locking bar 19, then shoving forwardly on thehandle 17 and associated rod 15 and afterward dropping the locking bar19 into engagement wlth the tooth bars and locking the said bar 19against disengagement. lVhen the tooth bars are in this position, asheretofore stated, their teeth project rearwardly and are out ofposition to have working engagement with the soil. It is preferable thata runner in the nature of a length of strap iron 27 be secured to theunder edge of each of the side sills 5 of the frame whereby the saidedges of the sills will not be worn due to travel over road and othersurfaces.

It will further be apparent from the fore going description of theinvention that its use, when not employed as a harrow, is not limited tothat of a drag, a log, a stone boat, or the like, but there are numeroususes to which it may be put.

1V hat is claimed is 1. In a harrow, a plurality of oscillatory toothbars, a swinging locking bar engaging with the tooth bars to hold thesame in one position or another, and means for holding the said lockingbar against disengagement from the tooth bars.

2. In a harrow, a plurality of oscillatory tooth bars, a swinginglocking bar having seats engaging with the tooth bars to hold the samein one position or another, means for holding the said locking baragainst disengagement from the tooth bars, and means whereby the toothbars may be simultaneously oscillated.

3. In a harrow, a plurality of oscillatory tooth bars, means forsimultaneously oscillating said bars, a pivoted locking bar engagingwith the tooth bars to hold the same in one position or another, and alatch bar cooperating with the said locking bar whereby to hold the sameagainst disengagement from the tooth bars.

4. In a harrow, a plurality of oscillatory tooth bars, means forsimultaneously oscillating said tooth bars, the said tooth bars beingpolygonal in cross section, a locking bar having polygonalrecesses'engaging with the tooth bars whereby to hold the same in oneposition or another, and means for holding the said locking bar againstdisengagement from the tooth bars.

5. In a harrow, a plurality of oscillatory tooth bars, a swinginglocking bar having seats engaging with the tooth bars to hold the samein one position or another, means for holding the said locking baragainst disengagement from the tooth bars, and means whereby the toothbars may be simultaneously operated, said means comprising bracketssecured upon the tooth bars and having upstanding apertured ears, and arod provided at points in its length with eyes having pivotal connectionwith the ears, the said rod being provided at one end with an upstandinghandle portion.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
